The apps stay free after the test
You're not unpaid QA for a future paid product. No ads, no accounts, no tracking, no in-app purchases — not during the test, not after release. The Google Play listing itself declares all of this.
A small favour. A real release.
I build small, private tools independently. Before Google lets a new app launch, real people need to join its closed test. Your place in that test makes the release possible—and your honest feedback makes the app better.
Free to join · Leave whenever you like · No review required
Google currently requires eligible new personal developer accounts to keep at least 12 testers opted in for 14 continuous days before applying for production access. Without that small group, an app cannot reach the public store.

You install from Google Play—not from an APK or an unfamiliar download page.
A fair question
If the word “free” makes you look for the hidden price, you've been paying attention. Look here as long as you like — this is all you'll find:
You're not unpaid QA for a future paid product. No ads, no accounts, no tracking, no in-app purchases — not during the test, not after release. The Google Play listing itself declares all of this.
Google enrols testers by Google account, so your address goes on the tester list and receives test updates — nothing else. No marketing, never shared, and you can leave the list whenever you like.
No review, no rating, no minimum usage. Install the app, stay opted in, and open it when you're curious — that is the entire job.
These apps earn nothing by design. Your opt-in gives me the one thing I can't buy or build myself: the small group of real testers Google requires before a free app may reach the public store.
That's the whole trade: fourteen days of your patience, and another genuinely free app — no subscription, no ads, no catch — becomes available to everyone.

Send the email for the Google account used on your Android device. I will add it to the tester list and email you when access is ready.
Use the app when convenient. Staying enrolled for 14 days is the part that unlocks a release; private feedback is a welcome bonus.
